Spawn Actor from Client and set its variables

Hello folkss!!!

Can somebody help me? save me? rescue me?

I am trying to make my client character Spawn a ammo box with what is left from it. the problem is that when i do that, even event replicated, the ammo box respaws with full ammo, not what is left from the client. i used to pass the variable but its not working, and tried to replicate the variable without sucess too.

get item stats from inventory>spawn actor by client on server rpc > set actor variables.
